ADJUSTABLE noon am Application med mvember 24, 192s.- semi No. 321,687.

This invent-ion relates to door and window frames having jambs adjustable for the urpose of making a proper fit with the stri ing ed e of the door in cases Wherethe door has i eit er shrunk or swollen beyond the size when it was first fitted and hung in its door frame.

The main object of the invention is to provide a door frame of ythis typel with adjustable parts which can be readily and cheaply made when the door frame is under process of manufacture. v

Another object of the invention is to provide a door frame of this type in which the adjustable jamb will not weaken the striking stile to any great extent and which may be readily adjusted by means of the ordinary screw driver.

Other objects of the invention will `become apparent as the detailed description thereof proceeds. In the drawings: I

Figure l is an elevation of a door hung in its frame with parts of the architrave on the striking side of the frame removed and the adjustable parts of the jamb shown in sectionv to illustrate the operation of the several parts of the invention;

Fi ure 2 is a vertical section on the line 2-2 of Figure 1, illustrating the adjustable jamb in elevation and the stop strip thereof in ele v vation and broken away;

Figure 3 is a horizontal section taken on the line 3-3 of Figure 1;

Figure 4 is a fragmentary vertical section:

illustrating a modified form of the means for adjusting the adjustable j amb;

Figure 5 is a fragmentary vertical section of another modified form of the jamb adj ustinv means; and l igure 6 is an exploded perspective of one of the adjusting screws and spring Washers adapted for use therewith.

vReferring to the drawings t,

The reference character 1 designates a door hin es 3 and 4. The hinged side and the top of` t e door frame may be of any usual construction. The stile 5 at the striking side of the door frame is constructed somewhat vdifferently in order to provide for the adjusthinged to a frame 2 by means of the usual ing of the door receiving recessed par-tof the frame to accommodate properly the door as it variesv in width according to weather conditlons.

lThe stile 5 is made up of a `solid part 6 secured in any suitable manner to a stud 7. The

part 6 extends evenly with the inner ed e I8 of the stop strip 9 and forms with the stu 7 a deeprecess 10 in which the Yadjustable jamb l11is,slidablyvmounted. l. The door frame may be provided with the usual architrave trim 12 and 1 3. 'The trim 13 is securely fixed to the stud 7 and extends beyond this stud toward the striking edge of the door and forms-with the part 6 a channel- .like recess in whichfthe part 11 slides. ,l

j At the Vbottom ofthe recess 10, the stud 7 is provided with a metal plate 14 which is tapped at intervals to receive the screwthreaded Shanks 15, projecting with free sliding lit into boresv 16 formed in the stud 7.

The back ofthe sliding jamb 11 is rovided withya metal plate 17 andv vlthis p ate is provided with apertures 18 in alinement with bores 19 formed inthe slidingy jamb 11.

Countersunk cups 2O are locatedin corre-l sponding countersinks 21 flush with the face of the jamb 11 and areadapted to receivey the head 22 of the adjusting screws. l y

`In the form of the invention illustrated in Figure 3 the screws are bored, just wherev the shank projects through the plate 17, 'and a cotter pin, or similar device, 23l is secured therein to form an abutment against the back of plate 17 which will prevent removal of the stud 7. This modification is shown in Fig-'- .ure 4.y

In the modification shown in Figure 5 the screws 25 are provided with annular recesses 26 adapted to receive split spring washers l27 to form holding abutments for the screws against the back of the plate 17.

The springs 24 are not necessary wherever the pins 23, or washers 27, are employed. However, it is preferable to use them in order to' prevent possibility of rattling of the parts and separation thereof.

It will be apparent from Figure 3 of the drawings, that the parts 6 and 7 may be made in one piece at the factory, and that lthe adjustable jamb 11 may bereadily assembled with the one piece part 6 and 7 and with the vface thereof alined with the face of the part 6.4 This adjustable jamb will then present no appearance different from the usual jamb except for the' showing of thehead of the screws and cups which are seated flush with the face of the adjustable jamb and provide for the adjustment thereof.-

The saddle or carpet strip'28 may be cut under the bottomend of the adjustable jamb so as to prevent the showing of the space between the saddle and the jamb, when the latter ma be adjusted toward the stud 7. However, t e adjustment of this jamb is usually so slight in one direction or the other that the saddle may be vfitted between the door jambs in the usual manner.v

The operation of the invention will be apparent from the drawings and need notpbe described in detail herein. Y A

While I have parts 6, 7 and 9 as separate pieces assembled to form thestriking stile of the door, it must be understood that these separate elements ma be formed integrally with each other in o'r er to facilitate factory assembling of the striking stile and the adjustable jamb. I have shown these elements section linedin the same direction to accentu-y ate this idea fand williclaim it accordingly.

What I claim is:. A door frame having at the strikiny side, a stile provided with a groove, ajam slid; ably'seated in said groove, screwsk arranged at intervals along sald jamb extending from the front, depth-wise through said jamb and t threadedly engagin the bottom wall of said oove, stops on sai y screws behind said j amb or pushing the latter outward whenl said l screws arebacked, and springs on certain of tom wall of said groove for taking uploose? said screws -between said jamb 'and the botness between said jamb and the heads and stops of said screws.

I testimony whereof I aiix my signature.

WILLIAM P. BRIGHT.
